ATTOR N EY Patented Nov. 29, 1932 l r HOWARD W.FORZBES AND EURES MITCHELL, F SWANTON, OHIO ADJUSTABLE SPUR PLATE FOR SHOES Application filed November 17, 1931. Serial No. 575,6 4.

Theobject of the invention is to provide a device adaptable to the sole of a shoe to the size of which it may be readily adjusted and which carries means that will prevent the user from slipping, as when playing golf,

footballer baseball, or where any occupation is engaged in that makes necessary insurance against slipping of the feet; and to provide a device of this character which is of such form that it may be produced by a stamping process and therefore manufactured cheaply, consisting of but few parts, so that it is unlikely to get out of order.

With this obj ectin view, the invention consists in a construction and combination of parts of which a preferred embodiment is illustrated in the accompanying drawing but to which the invention is not to be restricted further than is imposed by the appended claims.

In the drawings:

Figure 1 is a bottom plan view of a shoe showing the invention applied in operative position. y

Figure 2 is a side elevational view of the structure of Figure 1.

Figures 3 and 4c are bottom plan views respectively of the two complemental elements comprising the invention.

Figures 5 and 6 are sectional views on the plane indicated by the lines 5-5 and 66 respectively of Figure 1.

The invention comprises the complemental plates 10 and 11 of which each is formed at its opposite end with lateral extensions 12 terminating in upturned or substantially right-angularly disposed lip members .14

adapted, when the device is attached to the shoe 15, to embrace the side edges of the sole 16 thereof.

In addition to the lateral extensions 12, the

plate 10 is formed with the lateral extensions 17 and 18 of which the formeris provided 45. with a centrally disposed threaded hole 19 and the latter with an arcuate slot 20 terminating at one end in a lateral slot 21.

The plate 10. is so formed that the portion 18 lies in a spaced parallel plane from that of the main part of the. plate, so that when positioned on'topof the lateral extension 22 of the plate 11, the two. plates 10 and 11 may lie in a common plane. The extension, 22 of the plate 11 is formed with a threaded hole .23 and the/plate 11 is also formed. with a lateral extension 24 adapted to overlie the extension 17 of the plate 10. The extension 2 1, however, is pressed to dispose it in a plane parallel with the plane ofthe body portion plate 11, so that when disposed on top. of the extension 17, the two plates may lie in a com- .mon plane.

V The extension 2 1 is provided with an an .cuate slot 25 of which one edge is notched as itldicated at 26, throughout the length of the .s ot.

A, headed screw 27 passes through the slot '20 and threads into the hole 23, to hold the two plates together at the rear end, and a similar screw 28 passes through. the slot 25,

threading into the hole'19, this screw engaging one of the notches or seats 26, when the device'is attached to a shoe. In making the'attachment, both screws are loosened and the plates are moved away from each other until'the screw 27 is in the end of the slot 20 into the lateral portion 21 of which it may then be slid which will clear the screw 28 from any of the seats 26'with which it may have been engaged. The two plates at the forward end are then moved toward each other toposition the screw 28 opposite the slot or seat 27 which it may engage for the proper relative positions of the plates for the shoe'sole to be fitted; It is then slipped'into said, seat which will'result in moving the screw 27. out of the clearance extension 21,

28 moves out of the extension slot 21. The two "plates brought together to engage the lips on the shoe sole, the screw may then be tightened.

When the screw 27 is in the main portion of the slot 20, the screw 28 is perforce engaged with one of the seats 26, so that the two plates are rockingly mounted at this point and when the rear ends are moved together, the lips at the forward ends are brought into firm engagement with the shoe sole. Tightening ot the two screws 27 and 28 retains the plates in binding engagement with the screws.

Each plate 10 and llis provided with antislipping means which may be of any acceptable form desired but which, in the, illustrated embodiment, consist of spurs 29.

The invention having been described, what is claimed as new and useful is: p 7 l 1. A device for the purpose indicated comprising complemental plates formed with shoe sole engaging clips, each plate being tures.

formed with lateral extensions overlapping that of the other plate, one of said plates being provided with a stud adjacent one extremity of one extension and an arcuate slot extending substantially the length of the other extension and formed with the stud as a center, the lower edge of said slot being formed with a series of stud engagingseats, the other platehaving that extensionoverlapping the stud carrying extension of the first plate having an arcuate slot with a lateral extension at one end,"said stud traversing said arcuate slot and seating in said extension, the other extension of said second plate having'a stud traversing thearcuate slot in the extension of the first plate and being engageabl'e in any one of said seats therein when the stud on the first plate is in any position in the slot of the second plate, the'stud on r the second plate being disengaged from said seats when the stud of the firstplate is in the lateral extension of the slot on the second plate.
